Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, address the safety and operational standards of civil aviation in Australia. One such regulation is found in Part 39, which includes specific Airworthiness Directives to ensure aircraft safety. AD/SWSA226/40 is an example of such a directive, focusing on the Fairchild (Swearingen) SA226 and SA227 series aeroplanes. This directive was introduced to address the problem of engine flame-out and power loss due to the ingestion of propeller spinner ice, a significant safety concern following incidents reported overseas. The policy objective is to enhance flight safety by prohibiting flight into known icing conditions, as evidenced by the requirement to install a placard on the instrument panel stating "Flight into known icing conditions prohibited." Compliance with this directive is mandatory, requiring the placard to be installed within ten hours of the aircraft being in service after 17 December 1981.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates safety directives applicable to certain Fairchild (Swearingen) SA226 and SA227 series aeroplanes, particularly those not incorporating Fairchild Swearingen Corporation Service Bulletin No. 74-002. This regulation applies to specific serial numbers of the SA226-T, SA226-T(B), SA226-AT, and SA226-TC models, imposing a requirement for the installation of a placard prohibiting flight into known icing conditions. The placard must be installed on the instrument panel, clearly visible to the pilot, with a minimum lettering size of 1/4 inch. Compliance with this directive must be achieved within 10 hours of time in service following 17 December 1981. This directive stems from incidents of engine flame-out and power loss due to propeller spinner ice ingestion, as referenced in FAA Airworthiness Directive 81-24-04. The regulation is administered by the Civil Aviation Safety Authority under the Commonwealth of Australia, ensuring that the specified aircraft meet the safety standards to mitigate risks associated with known icing conditions.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 (subsections) mandate a placard installation on certain Fairchild (Swearingen) SA226 and SA227 series aeroplanes (subsection 2). This placard must state, in a minimum 1/4 inch lettering, “Flight into known icing conditions prohibited” and be placed on the instrument panel in a position where it is plainly visible to the pilot. This requirement is applicable to specific models and serial numbers of SA226-T, SA226-T(B), SA226-AT, and SA226-TC aeroplanes that do not already incorporate Fairchild Swearingen Corporation Service Bulletin No. 74-002 (subsection 3).
The obligations imposed by this regulation are straightforward. Operators of the specified aircraft models must ensure that the placard is installed within 10 hours of the aircraft being in service after 17 December 1981 (subsection 4). This ensures that pilots are aware of the prohibition on flying into known icing conditions, which is a critical safety measure.
The consequences of non-compliance with this directive are not explicitly detailed in the provided text, but it is reasonable to infer that failure to adhere to this safety requirement could result in penalties under civil aviation laws. Such penalties could include fines, aircraft grounding, or other administrative actions that the Civil Aviation Safety Authority might impose to enforce compliance with safety regulations. The specific penalties would depend on the broader context of the Civil Aviation Regulations 1998 and any additional legislative provisions that might apply.
